I was on my way to a party bash with my girlfriends and some of their partners, i got lost AND stuck in traffic. I was absolutely busting for a pee and had to ask my girlfriend as soon as i got there. I rushed upstairs to the bathroom and at the last moment remembered i was wearing my harem style pants with the drawstring which occasionally knotted when i pulled the string. Too desperate to think straight i pulled the string as i closed the loo door but oh dear, it knotted! Foolishly i pulled harder, which achieved nothing except knotting it more tightly. Without undoing that knot i could NOT get my pants down! I was just about wetting myself and knew i couldn't possibly wait til i'd patiently struggled to untie the knot. So i pulled my pants up tight and sat on the toilet and weed through my pants. It was my only possible option but at least i avoided it going all down my legs, there was only a wet patch right at the crotch and no one noticed when i went down to the party - at least i don't think they did! No one said anything at least. I couldn't help it, that was all i could do!!
